Rio has two airports and you may not have a choice: it depends on your flight. If you do, these are the differences.
Galeao (GIG)
The international airport, with more connections, in the north of the city. It is the most-used route. See Galeao to Buzios transfer.
Santos Dumont (SDU)
Downtown, with domestic flights. Useful if you come from another city in the country. See Santos Dumont to Buzios transfer.
A third option: Cabo Frio
Cabo Frio airport is much closer to Buzios. Check whether your airline flies there: Cabo Frio transfer.
How to decide
- Flight price and times.
- Whether you need an international connection.
- Your arrival hour: at night, it is better to avoid downtown traffic.
